Auto Style Selection

When no --style is specified, the system analyzes content to select the best style:

File Management

With Article Path

Save to [source-name-no-ext]/cover-image/ subdirectory in the same folder as the article:

path/to/
├── article.md
└── article/
    └── cover-image/
        ├── prompts/
        │   └── cover.md
        └── cover.png

Example: /posts/ai-future.md → /posts/ai-future/cover-image/

Without Article Path (Pasted Content)

Save to ./cover-image/[topic-slug]/:

cover-image/
└── ai-future/
    ├── source.md           # Saved pasted content
    ├── prompts/
    │   └── cover.md
    └── cover.png

Directory Backup

If target directory exists, rename existing to <dirname>-backup-YYYYMMDD-HHMMSS

Workflow

Step 1: Analyze Content

1. Save source content (if not already a file):

   • If user provides a file path: use as-is
   • If user pastes content: save to source.md in target directory

2. Extract key information:

   • Main topic: What is the article about?
   • Core message: What's the key takeaway?
   • Tone: Serious, playful, inspiring, educational?
   • Keywords: Identify style-signaling words

3. Language detection:

   • Detect source language from content
   • Detect user language from conversation context
   • Note if source_language ≠ user_language (will ask in Step 3)

Step 2: Determine Options

1. Style selection:

   • If --style specified, use that style
   • Otherwise, scan content for style signals and auto-select 3 candidates
   • Default to elegant if no clear signals

2. Aspect ratio:

   • If --aspect specified, use that ratio
   • Otherwise, prepare options: 2.35:1 (cinematic), 16:9 (widescreen), 1:1 (social)

Step 3: Confirm Options

Purpose: Let user confirm all options in a single step before generation.

IMPORTANT: Present ALL options in a single confirmation step using AskUserQuestion. Do NOT interrupt workflow with multiple separate confirmations.

Determine which questions to ask:

Present options (use AskUserQuestion with all applicable questions):

Question 1 (Style) - always:

• Style A (recommended): [style name] - [brief description]
• Style B: [style name] - [brief description]
• Style C: [style name] - [brief description]
• Custom: Provide custom style reference

Question 2 (Aspect) - always:

• 2.35:1 Cinematic (Recommended) - ultra-wide, dramatic
• 16:9 Widescreen - standard video/presentation
• 1:1 Square - social media optimized

Question 3 (Language) - only if source ≠ user language:

• [Source language] (matches content)
• [User language] (your preference)

Language handling:

• If source language = user language: Just inform user (e.g., "Title will be in Chinese")
• If different: Ask which language to use for title text

Step 4: Generate Cover Concept

Create a cover image concept based on selected style:

Title (if included, max 8 characters):

• Distill the core message into a punchy headline
• Use hooks: numbers, questions, contrasts, pain points
• Skip if --no-title flag is used

Visual Elements:

• Style-appropriate imagery and icons
• 1-2 symbolic elements representing the topic
• Metaphors or analogies that fit the style

Step 5: Create Prompt File

Save prompt to prompts/cover.md with confirmed options.

All prompts are written in the user's confirmed language preference.

Prompt Format:

Cover theme: [topic in 2-3 words]
Style: [selected style name]
Aspect ratio: [confirmed aspect ratio]

[If title included:]
Title text: [8 characters or less, in confirmed language]
Subtitle: [optional, in confirmed language]

Visual composition:
- Main visual: [description matching style]
- Layout: [positioning based on title inclusion and aspect ratio]
- Decorative elements: [style-appropriate elements]

Color scheme:
- Primary: [style primary color]
- Background: [style background color]
- Accent: [style accent color]

Style notes: [specific style characteristics to emphasize]

[If no title:]
Note: No title text, pure visual illustration only.

Step 6: Generate Image

Image Generation Skill Selection:

1. Check available image generation skills
2. If multiple skills available, ask user to choose

Generation: Call selected image generation skill with prompt file, output path, and confirmed aspect ratio.

Step 7: Output Summary

Cover Image Generated!

Topic: [topic]
Style: [style name]
Aspect: [aspect ratio]
Title: [cover title] (or "No title - visual only")
Language: [confirmed language]
Location: [output path]

Preview the image to verify it matches your expectations.

Notes

• Cover should be instantly understandable at small preview sizes
• Title (if included) must be readable and impactful
• Visual metaphors work better than literal representations
• Maintain style consistency throughout the cover
• Image generation typically takes 10-30 seconds
• Title text uses user's confirmed language preference
• Aspect ratio: 2.35:1 for cinematic/dramatic, 16:9 for widescreen, 1:1 for social media

Extension Support
